I'm not sure that mead in English is the same as sima. Mead is a honey-based drink and has many varieties. It might be better to also accept "sima" as an answer if there is no direct, unique equivalent
The Finnish sima has historically had honey in it, but these days it's most often made with lemons and dark brown sugar. Close enough, I guess?
It's... not, but Finns refer to it as mead when speaking English. So it is a phrase you may hear spoken in Finland in the spring.
I typed "Kaksi pullaa simaa kiitos" by accident and it accepted it as a correct answer when it probably should not have.
They accept typos. But some times it's annoying.
